Increased Error-Related Brain Activity in Six-Year-Old Children with Clinical Anxiety

Anxiety disorders are the most frequently diagnosed form of psychopathology in children and often result in chronic impairment that persists into adulthood. Identifying neurobehavioral correlates of anxiety that appear relatively early in life would inform etiological models of development and allow intervention and prevention strategies to be implemented more effectively. The error-related negativity (ERN), a negative deflection in the event-related potential at fronto-central sites approximately 50 ms following the commission of errors, has been consistently found to be larger among anxious adults. The current study sought to extend these findings to even younger individuals: the ERN was elicited by a Go/NoGo task in 48 six year-old children with a clinical anxiety disorder assessed by diagnostic interview and 48 age-matched controls. In addition to child anxiety disorder, the ERN was examined in relation to maternal history of anxiety disorder, which was previously related to a smaller ERN. Anxious children were characterized by a larger (i.e., more negative) ERN and maternal history of anxiety disorder was associated with a smaller ERN. Thus, the relationship between an increased ERN and clinical anxiety is evident by age 6, and this effect appears independent from an opposing influence of maternal anxiety history on the ERN. These findings support the ERN as a promising neurobehavioral marker of anxiety, and implications are discussed.

Student gender and the probability of referral for counselling in a college of further education

A small pilot study was carried out to investigate whether college tutors' perceptions of students' counselling needs were dependent on the gender of the student. Twenty-five tutors were asked to read six vignettes describing composite case-studies of students showing overt distress. The vignettes were constructed to represent two of each of three types of problem (anxiety, depression and aggression). One of each clinical type depicted a female student and the other a male. The tutors were asked to evaluate each of the six vignettes along a visual analogue scale, according to the perceived urgency of the problem and its long-term nature. The results were then analysed using two-factor within-subjects anovas and unplanned multiple pairwise comparisons to establish whether there existed any differences on these dimensions. Of the analyses computed, it was found that depressive vignettes were considered to be in more urgent need of referral than were anxious or aggressive vignettes; that males were generally considered to have a more urgent need for referral than were females; that anxiety was construed as a less enduring problem than was depression or aggression; and that male aggressive vignettes were considered to be a longer-term problem than were females, anxious or depressive clients. These results indicate that some sex-role stereotyping exists with respect to psychological problems. This is discussed in terms of equal opportunities and access to student support systems.     

Testing a Moderated Mediation Model of Objectification Theory among Black Women in the United States: The Role of Protective Factors

Recent studies find that Black women experience rates of eating pathology and body dissatisfaction comparable to those of White women. Abundant research suggests that objectification theory could help explain the development and maintenance of eating disorder (ED) symptoms among diverse women. However, research on the applicability of objectification theory to ED symptoms in Black women is equivocal. Specifically, some have suggested that body surveillance might operate differently for Black women. Thus, the current study examined ethnic-racial identity (ERI) commitment and body appreciation as moderators of the mediated associations among body surveillance, body shame, and ED symptoms. Black women (n?=?175) in the United States completed measures of body image, ERI commitment, and ED symptoms. Consistent with objectification theory, body shame mediated the association between body surveillance and ED symptoms. Contrary to our hypothesis, ERI commitment did not moderate the link between body surveillance and body shame. However, body appreciation was a significant moderator, such that the strength of the relation between body surveillance and ED symptoms via body shame was weakened at high levels of body appreciation. Future work should consider interventions that foster body appreciation in Black women.

The Caregivers of Stroke Patients: An Investigation of Factors Associated with Depression

Caregivers of the elderly and infirm are often under more stress and report lower life satisfaction than matched groups of noncaregivers. Forty caregivers of stroke patients (usually a spouse) were interviewed an average of 9 months poststroke to determine the factors associated with poorer caregiver adjustment. Four classes of variables were expected to be related to depression in caregivers: level of functioning of the patient, caregiver perceptions of increased work and burden due to the stroke, the quality of the patient-caregiver relationship, and caregivers' interpretations of their situation. Background characteristics were also measured. As predicted, variables in each class were significantly related to depression. Multiple regression analysis showed three significant independent predictors of caregiver depression. Caregivers are more depressed if the patient is more physically impaired, if caregivers report disharmony in the family, and if they have lesser perceptions of hope Ways to apply these findings to the development of interventions to ameliorate caregiver depression are discussed.     

Maintaining global coherence in reading: The role of sentence boundaries

In four experiments, we examined the reinstatement of backgrounded information in locally coherent passages, investigating the influence of syntactic boundaries, such as periods, on the time course of this process. In Experiment 1, using a line-by-line reading paradigm, readers were delayed in noticing a contradiction on a target line when the sentence continued onto a posttarget line. Consistent with this, in Experiments 2A and 2B, the results of a recognition probe demonstrated that relevant concepts from long-term memory were not integrated immediately unless the contradiction was followed by a period. Experiment 3 demonstrated that sentence boundaries are sufficient to facilitate the integration of related background information but are not necessary; additional time served the same purpose. Consistent with a memory-based text-processing framework, it appears that the reactivation of related information is initiated automatically but that an integration stage is influenced by such factors as syntactic boundaries.     

The role of playing and efference in the recall location and distance cues in short-term motor memory

Previous studies have suggested that the superior accuracy of preselected (subject-defined) over constrained (experimenter-defined) movements is due to both the availability of a movement plan and efferent-command information. The present experiment examined the contribution of the planning and efferent components to the preselection effect in a location and a distance task. The availability of a movement plan was manipulated by providing preselected and constrained groups of subjects with a rehearsal movement. Furthermore, the amount of efferent information available was varied by requiring both active and passive rehearsal movements. The results suggested that while strategy alone is responsible for the superiority of preselected location, both strategy and efferent information underlie the superiority of preselected distance reproduction.     

Perceptions of Overprotection in III Adults1

Several studies have suggested that chronically ill adults who receive overprotective care are more depressed and less motivated in rehabilitation therapy. However, for this area of research to proceed, a standard definition and measurement of perceptions of overprotection are needed. In the present study, long and short forms of a scale (the OPSA) to assess perceptions of being overprotected in chronically ill adults were developed. The scale's psychometric properties were tested with a sample of 161 community-dwelling older adults. It was found to have good internal reliability, to correlate highly with an established retrospective measure of overprotection in adults, and to be distinct from ratings of quantity and quality of social support. As expected, overprotection was associated with poorer adjustment: Respondents who felt overprotected were more depressed.     

Articulatory suppression and the treatment of insomnia

The prominence of intrusive thoughts in insomnia suggests the relevance of cognitive techniques to control them. It is suggested that the technique of Articulatory Suppression derived from Baddeley's model of Working Memory provides a relevant approach. The technique is presented as it was developed with a preliminary uncontrolled case series. A single-case experiment is then reported in which Articulatory Suppression was compared with other techniques. The preliminary indications are that it may be particularly helpful for sleep maintenance problems.
